First of all why do you think you've overfed your lady? She looks great.. Nice colors throughout. I'm seeing yellowing leaves which could be a sign of underfeeding... I'd like to help you if you think I can. Pm me and we can get it figured out. Flushing is kind of a last resort sort of deal.
I don't really see any signs of overfeeding here.. why do you think you overfed them?
I don't see nutrient-burn, or the excessive darkening of too much nitrogen.
